TO ALL WHOM IT MAY CONCERN:

Be it known that I, E. S. BARNES, of Nebraska City, in the county ofOtoe, and State of Nebraska, have made certain new and usefulImprovements in Propelling-Apparatus for vessels and other purposes; andI do hereby declare that the following is a full and clear descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

This invention has two general features, the first of which relates toa. device for transmitting reciprocating motion, and the other to adevice for feathering the paddles, the latter being susceptible of areversing-attachment.

To enable those skilled in the art to make and use my improvedapparatus, I will proceed to describe its construction and operation.

Figure 1, of the drawings, is a general plan of the apparatus. This viewbeing designed more especially to illustrate the general features of theinvention, the reversing-apparatus is not shown.

Figure 2 is an enlarged elevation of one end of the propelling-machine,showing the feathering-apparatus in detail.

Figure 3 is a top plan of the same parts shown in fig. 2.

Figure 4 isa rear elevation of the same parts shown in iigs. 2 and 3.

A and A are two sliding ways, one of which may be attached to the sideof the hull of a vessel, and the other may be secured to theout-riggers, as in the case of a bridge-tree. On each end of thesesliding ways are placed sliding` heads, B B, the inner faces of thesesliding heads being cogged, for the reception ofthe cogs ofthe sectorsC, and to these cogged sectors are attached the paddles, D. The twosliding heads are connected together by means of the reciprocating`jointed connecting-rods or barsD. These rods or bars are formed ofshort pieces, d, which are united in pairs by means of the' central pinsdi, and the several pairs of them are connected together by means of theouter pins d2. About midway of this jointed connecting-rod it issecured, by means of a fixed pivot-pin,- cl3, to the transverse bar D?,which is firmly secured to the side-ways AA. The connecting-rod of theengine, or other motive-power, is to be attached to the joint d* bymeans o f-the bar D3, or by some other suitable attachment. I

The eentral joint d3being fixed, itis evident that, as thejoint-pin d*is moved forward and backward, the sliding heads B B willfbe operated ina reciprocating manner, being alternately dra-wn toward andpushed fromthe centre-pin cl3. As the paddles D are attached to and moved with thesliding heads B B, as will hereinafter morefu'lly app-ear, and as bothof these said sliding heads are drawn toward and pushed from thecentre-pin cl3 simultaneously, it is evident that one of the saidpaddles will be moving forward at thesame time that the other one ismoving backward, and, therefore, one of the said paddles will be actingupon the water to propel the vessel forward, while the other paddle isreturning in a feathered position for a new hold in the water, as willbehereinafter more fully described. As is clearly shown in iig. 2, thereare two cogged sectors, C C1, attached to the central part of thesliding head B. To the upper one of these sectors, C, the paddle Disfirmly secured. This sector gears into theco'gged rack c, which, as thesliding head is moved forward and backward, as it'nears the end of eachstroke, is engaged by the tappcts t" c2 onlthe sliding rod Cz, andthereby the said rack isimoved back, the sector is turned partly l"over,and the paddle D is either feathered or turned down for a hold in thewater, as the cased may be. The

sec'tor' C forms a semicircle, and at each end of the stroke it makes aquarter turn, as above described.

The sectorCl forms a. quarter circle, and it is placed directly belowthe sector C, so that the straight face of the latter may rest on theformer, and hol-d it rigidly during the forward motion of the paddle.This sector C1 may be turned over, so as to form a rest for the sectorC, on either side, by means of-the cogged rack c3. This rack c3 isattached to the side of the sliding head B by means of the pendants c4,and the spring-hooker5 secure the said rack to the said sliding head ateither end, as may be desired for a forward or a backward stroke` of thepaddle. The hooks c5 will hold the rack c3 in whichever position theymay be placed, until they strike one of the tappets c6 c7 on the rod C3.

This sliding rod and its tappets may be moved to either end, ashereafter described, even while the machinery is under full headway, andthe sliding rack will, by comingin contact with the said tappets, bemoved in. accordance with the adjustment thereof, and the sector C, andits paddle D, will, in compliance with the said adjustment of' thesector C1, befeathered, either fora forward or a backward stroke.

As isQclearly shown in g. 4, the sliding rods CZ Cshave short coggedsections z8 a9, which are engaged by the cogged sectors E El, which areattached" to the operating-lever E2. This lever may have arope or chainattached to its outer end, and the said rope or chain conducted to. thepilot-house, or other convenient portion of a vessel, where the properoicer may turn the lever tol either side, at pleasure, and therebyshift'the positions of the rods Cz G3 and their tappets, therebychanging the positions of the sectors C G1, as above described, andsetting the paddle D, so as to feather in either direction, for a.forward or a backwardxstroke.

Having described my invention, what I claim, is- Y 1. The cogged'sectosC C1, in combination with the paddle D, when arranged andv operatedsubstantially y as set forth.

2. The combination of the reversing-sectors E El and their operating-barE2, when acting to operate the bar G3 and rack-c3, for feathering thopaddles at either end of stroke, and reversing the same, substantiallyas Y set forth.
